First the location - great and safe neighborhood. Bonus - a short walk to the BTS station.
The apartment is not brand new but everything works and most importantly it is clean.
Finally the host. You can't ask for a more friendly, helpful and charming host who was always very prompt in responding to my concerns. And English is not an issue at all - his command of the English language is way better than mine.
I will definitely return - assuming this super host will have me back.
